Analysis of measured parameters of the cardiovascular system
Lysoň, Jakub ; Vítek, Martin (referee) ; Kratochvíla, Jiří (advisor)
This bachelor thesis talks about the measurement of heart electrical activity by twelve lead ECG. The diagnostic system Biopac is used for measurement, featured by the computer program Acqknowledge. The own authentic method is designed to detect effect of load on increasing in blood pressure and heartbeat. Using a statistical procedure for testing hypotheses in this area the measurement results will be evaluated. For the analysis of measured data in time and frequency domain was used program Matlab, in which the measured results were imported. It was created functions that are implemented in an medium of Guide to the graphic design program.

Processing of a continual blood pressure signal
Svobodová, Ivana ; Soukup, Ladislav (referee) ; Vondra, Vlastimil (advisor)
Bachelor thesis contains a general description of the blood pressure phenomenon and its importance and also deals with diseases, such as hypotension and hypertension. The work also includes a literature review of blood pressure measuring methods. Closely are discussed the non-invasive methods. The result of the work is also a unique program designed in Matlab, which is developed for signal processing of continuous blood pressure measurement for detection of SBP and DBP and MAP, pulse after pulse. To verify the functionality of the program, the further implementation was carried out in GUI. In conclusion, the obtained data are beeing analyzed statistically.

Causal interaction analysis of cardiovascular signals
Tiurina, Mariia ; Kolářová, Jana (referee) ; Svačinová, Jana (advisor)
Application of the non-invasive methods to detection of the baroreflex sensitivity is a correct way to evaluate the functions of cardiovascular system. This master’s thesis describes the theoretical informations about the problem of baroreflex sensitivity from anatomical, patalogical and clinical views. Theoretical knowledges are foundation for mathematical description of some methods to detection of baroreflx sensitivity in time, frequency and information dimensions. In the practical part of the master’s theses are presented two methods of BRS detection – sequence method based on finding the specific sequences of time series signals and method of application bivariante autoregressive model. Both of methods are implemented in MATLAB. The results of testing data on real data are discussed.

Polygraphic measurement of stress
Faltýnková, Květoslava ; Kolář, Radim (referee) ; Bubník, Karel (advisor)
This work deals with polygraphic measurement of stress. The paper describes the physiological manifestations of stress induced as a result of false answers to the question and ways to measure these phenomena. It focuses mainly on changes in heart rate, blood pressure, respiration and skin resistance. It is designed to work in the block diagram of polygraph, described the course of measurement and evaluation. The work is also mention of lie detection using EEG.

Blood pressure estimation using smartphone
Vařečka, Martin ; Vítek, Martin (referee) ; Němcová, Andrea (advisor)
Blood pressure is one of the basic indicators of the health state of the cardiovascular system. High blood pressure is the main risk factor of ischemic heart disease, atherosclerosis and stroke. Therefore, it is important to monitor long-term changes in blood pressure and respond in time to these changes. Blood pressure meters are not standard household equipment, while a well-equipped smartphone is. Smartphones contain a large number of sensors capable of measuring biomedical signals. This thesis focuses on creating an application capable of determining blood pressure using data obtained from these sensors.

Measurement and analysis of cardiovascular parameters
Filipová, Petra ; Smital, Lukáš (referee) ; Kratochvíla, Jiří (advisor)
This bachelor´s thesis illustrates the basic diagnostic procedures for ECG analysis in clinical practice. It contains the verification of statistical hypotheses, automatic detection of the RR intervals using three different QRS detectors and heart rate from the ECG und other analyses in time and frequency domain. The validation of detection efficiency is investigated. Heart rate variability analyses are shown in time and frequency domain too. Analyses are done in Matlab, the graphical interface in Maltab GUIDE was done too and includes all of the created functions in time and frequency domain. For the purpose of evaluation methods the real data were measured according to the created acquisition protocol.

The measurement of cardiovascular parameters
Žáková, Monika ; Kratochvíla, Jiří (referee) ; Nováková, Zuzana (advisor)
This paper summarizes the problems of physiology of the cardiovascular system, with a focus on cardiovascular measurements during physical activity. It describes the diagnostic tools Cardiovit AT-104 (Schiller, Switzerland) and PowerCube (Ganshorn, Germany), used to spiro-ergometry measurements. It provides options to export data and work with them. It proposed protocol for the measurement of a small group of volunteers, by which we measure basic diagnostic parameters before, during and after physical activity. The MATLAB application is created, allowing clear analysis of measurement records. The final part contains a statistical assessment affected by physical activity on the measured parameters and a comparison of results with the available literature.
